Description

technical field [0001] The invention relates to the technical field of tire rubber, in particular to an ultra-high thermal conductivity tire vulcanization bladder rubber composition and a process for producing the bladder. Background technique [0002] As we all know, the production of tires needs to go through multiple processes such as mixing, extrusion, calendering, molding, and vulcanization. In the vulcanization process, the green tire is put into the vulcanization mold, and after a certain time, temperature and pressure, the tire vulcanization is completed. The tire is in the vulcanization mold, the external heat is transmitted to the outer surface of the tire through the steel mold, and the internal heat is transmitted to the inner surface of the tire through the curing bladder. Under the joint action of external and internal heat and pressure, the rubber molecules are chemically cross-linked , the embryo becomes a tire containing steel wires and fiber cords inside. ...
